Question for those who know:
When will there be proper ISS coverage of Titan's North Pole? All the maps upto now only show upto 30 degrees and the t4,T5 flybys only have a bit upto 60 degrees latitude, but that has probably a too high emission angle to see a lot of detail ( http://saturn.jpl.nasa.gov/multimedia/imag...fm?imageID=1479 ) there might be lots of clouds, since it's very cold out there at the pole (much more so than the south) and I'm pretty curious about them:) |

something I noticed a while ago...
http://saturn.jpl.nasa.gov/multimedia/imag...fm?imageID=1666 The lack of North polar (well...above 30 degrees, below 60 degrees) surface images seems more like a haze/phase angle issue than a lack of sunlight. |

The reason I don't include it on any maps it because of an emission angle issue. The haze makes it difficult to see terrain outside of 45 degrees emission angle unless the surface contrast is high. If the north polar region and northern mid-latitudes are anything like the southern hemisphere, than contrast is low, making observing features there when sub-spacecraft points rarely exceed 10N (for inbound coverage) difficult at best. -------------------- &@^^!% Jim!
